Hi i have some variables in one file - index.php looking like this:

$kPoln = floor(($getPoln*255)/$max);
$kPolnW = floor(($PolnW*255)/$max);
$kWsch = floor(($getWsch*255)/$max);
$kPoldW = floor(($PoldW*255)/$max);
$kPold = floor(($getPold*255)/$max);
$kPoldZ = floor(($PoldZ*255)/$max);
$kZach = floor(($getZach*255)/$max);
$kPolnZ = floor(($PolnZ*255)/$max);

and i want to send them to another file - image.php - it will serve as colors on some image, and that image will be displayed on index.php, how to do this??

include 'index.php';//will try to include, will continue if cant find
include_once 'index.php';//will only include it once, will continue if cant find (wont include the same file if it is called more than once)

require 'index.php';//tries to include, fatal error thrown if fails script will not run
require_once 'index.php';//tries to include once, fatal error thrown if fails script will not run (wont include the same file if it is called more than once)

you should make a variables file like inc.php

which contains the variables the pages will share, index.php sounds like a page that will have lots going on in it so isn't a good idea to include into another

inc.php
<?php
$colours = array(0=>'#ff8888',1=>'#88ff88',2=>'#8888ff');
?>
--------------

index.php
<?php
include 'inc.php';

echo $colours[1];
?>
-----------------------------------

image.php
<?php
include 'inc.php';

echo $colours[2];
?>

if its not that you could try doing an include like:
include('inc.php');

otherwise it's going to be a server error such as includes being turned off, you can check by typing:

phpinfo();

into a php file and it will output the current php settings on the server, it will say if includes are allowed or not

Member Avatar for Drugsxxx

i think it has to do something with image png.

Member Avatar for Biiim

Sorry i missed you had updated and replied

are you using imagepng() on the page?

if you are trying to pull and display an image with php you put it into a separate file eg.

image.php
<?php
header('content: image/png');

//do stuff to get image
imagepng($img);
?>
---------------------------
index.php

..html stuff...
<img src='image.php'/>
...html stuff...

imagepng prints out raw image data so if used while displaying html content type you will get that

Member Avatar for Drugsxxx

Still i would need to send variables to that image.php and i dont know how.

Member Avatar for diafol

something like this?

<?php
$getPoln = 200;
$PolnW = 1;
$getWsch = 233;
$PoldW = 10;
$getPold = 189;
$PoldZ = 39;
$getZach = 11;
$PolnZ = 167;

$max = 11;

$params = array(
	'kPoln' => floor(($getPoln*255)/$max),
	'kPolnW' => floor(($PolnW*255)/$max),
	'kWsch' => floor(($getWsch*255)/$max),
	'kPoldW' => floor(($PoldW*255)/$max),
	'kPold' => floor(($getPold*255)/$max),
	'kPoldZ' => floor(($PoldZ*255)/$max),
	'kZach' => floor(($getZach*255)/$max),
	'kPolnZ' => floor(($PolnZ*255)/$max)
);
foreach($params as $k=>$v){
	$p[] = "$k=$v";	
}
$qs = implode('&',$p);

well i could be something like this i think but how i use them in image.php??

Coz in image.php i have tu use those eight variables to color the circle.

Edited by Drugsxxx because: n/a
Member Avatar for diafol

The colours are passed to the image.php file in the querystring:

<img src="image.php?kPoln=4636&kPolnW=23&kWsch=5401&kPoldW=231&kPold=4381&kPoldZ=904&kZach=255&kPolnZ=3871" />
Member Avatar for Drugsxxx

yeah i now but in image.php variables must have the same name or i am missing something??

Member Avatar for diafol

The image.php will accept:

$_GET['kPoln']
$_GET['kPolnW']

etc

Member Avatar for Drugsxxx

Well its still nothing so i am thinking that i will show my code in those 2 files and maybe this will be better

co index.php looks like this:

<html>
	<head>
		<title></title>
	</head>
	<body>

<form action="index.php" method="post">
    <label for="datefrom">From:</label>
    <input type="date" id='datefrom' name="datefrom" />
    <label for="dateto">To:</label>
    <input type="date" id='dateto' name="dateto" />
    <input type="submit" name="submit" id="submit" value="Get Entries" />
</form>
<?php
$list = "";
if(isset($_POST['submit']))
{
$datefrom = $_POST['datefrom'];
$dateto = $_POST['dateto'];
 
$datefrom = $datefrom . " 00:00:00";
$dateto = $dateto . " 23:59:59";
 
$lines = file('KierunekW.txt');
foreach($lines as $line){
   	$r = explode(",",$line);
   	if(strtotime($r[0]) >= strtotime($datefrom) && strtotime($r[0]) <= strtotime($dateto))$list .= "\n\t<li>{$r[1]}</li>";
}
if($list !="")$list = "\n<ul>$list\n</ul>";
}// counting occurences of same strings
$getText = $list;
$Poln = substr_count($getText ,"Polnoc");
$PolnW = substr_count($getText ,"Polnocny-Wschod");
$Wsch = substr_count($getText ,"Wschod");
$PoldW = substr_count($getText ,"Poludniowy-Wschod");
$Pold = substr_count($getText ,"Poludnie");
$PoldZ = substr_count($getText ,"Poludniowy-Zachod"); 
$Zach = substr_count($getText ,"Zachod");
$PolnZ = substr_count($getText ,"Polnocny-Zachod");
$getPoln = $Poln - $PolnW - $PolnZ ;
$getPold = $Pold;
$getZach = $Zach - $PoldZ - $PolnZ ;
$getWsch = $Wsch - $PoldW - $PolnW ;
//max this value
$max = max(array($getPoln,$PolnW,$getWsch,$PoldW,$getPold,$PoldZ,$getZach,$PolnZ)); 

if($max!=0 && $getPoln!=0  && $PolnW!=0 && $getWsch!=0 && $PoldW!=0 && $getPold!=0 && $PoldZ!=0 && $getZach!=0 && $PolnZ!=0)
{
// Now i count a color value
$params = array(
	'kPoln' => floor(($getPoln*255)/$max),
	'kPolnW' => floor(($PolnW*255)/$max),
	'kWsch' => floor(($getWsch*255)/$max),
	'kPoldW' => floor(($PoldW*255)/$max),
	'kPold' => floor(($getPold*255)/$max),
	'kPoldZ' => floor(($PoldZ*255)/$max),
	'kZach' => floor(($getZach*255)/$max),
	'kPolnZ' => floor(($PolnZ*255)/$max)
);
foreach($params as $k=>$v){
	$p[] = "$k=$v";	
}
$qs = implode('&',$p);


}else
{
echo 'variable is 0';
}
?>
<img src="image.php?<?php echo $qs;?>" />
	</body>
</html>

and in the image.php it goes like this

<?php

$kPoln = $_GET[ 'kPoln' ]; 
$polb = $_GET[ 'kPolnW' ]; 
$polc = $_GET[ 'kWsch' ];
$pold = $_GET[ 'kPoldW' ];

$polf = $_GET[ 'kPoldZ' ];
$polg = $_GET[ 'kZach' ];
$polh = $_GET[ 'kPolnZ' ];
// set the HTTP header type to PNG
header("Content-type: image/png"); 
 
// set the width and height of the new image in pixels
$width = 550;
$height = 550;
 
// create a pointer to a new true colour image
$im = ImageCreateTrueColor($width, $height); 
ImageAntiAlias($im, false);
$white = ImageColorAllocate($im, 255, 255, 255); 
ImageFillToBorder($im, 0, 0, $white, $white);


 
//colors
$b = ImageColorAllocate($im, 0, 100, 255);
$t = ImageColorAllocate($im, $pola, $pola, $pola); // i woul like to use variables from index.php here
//next other colors

imagesetthickness($im, 2);
// draw an empty circle
ImageEllipse($im, 150, 150, 300, 300, $b);
//Lines on circle - borders
ImageLine($im, 95, 10, 205, 290, $b);
ImageLine($im, 205, 10, 95, 290, $b);
ImageLine($im, 10, 95, 290, 205, $b);
ImageLine($im, 10, 205, 290, 95, $b);

//filling with color
imagefilltoborder($im, 150, 50, $b, $t);
//next for other filling
ImagePNG($im); 
ImageDestroy($im); 
?>

kind of big post but realy dont know what to do with those variables sending/using

Edited by Drugsxxx because: n/a
Member Avatar for diafol

You've got them, but you don't use them:

$t = ImageColorAllocate($im, $pola, $pola, $pola);

You're using $pola - which doesn't seem to exist

Member Avatar for Drugsxxx

Right right - its working, my mistake.

I have one more question coz now before i enter the date in fields i have red "x" in a place of where image should be (he dont have variables to draw). Is there a way to not showing for this red x??(maybe in if function)

Member Avatar for diafol

It would be easier to not show the image at all on the index.php page:

<?php
if(...parameters/variables exist...){
   echo "<img src=\"image.php?$qs\" />";
}
?>

OR you could show a default 1x1 transparent gif via the image.php script. However, this would make little sense as a screen reader / view source would tell you that something was there - but you'd be a naughty little thing and would be tellings fibs.

Member Avatar for Drugsxxx

It is working but could it be in div?? i would like to align this on center of page

Member Avatar for Buppy

You can use them from URL as
$_GET
$_GET
etc..

Member Avatar for Drugsxxx

Oki on local server it works fine - i use xampp but on web it show me a red x, what could be wrong??

Edited by Drugsxxx because: n/a
Member Avatar for Drugsxxx

I could edit my last post but the problem with red x is Call to undefined function: imageantialias() it somthign with GD but i dont know how to fix it

Member Avatar for diafol

Is gd loaded? Are you tunning a really old v of php. See what's available with phpinfo()
